Colleague Peter Kim and I got into an interesting discussion on Twitter today. Turns out that he uses autofollow, while I don't. Now before you take sides on this—I'd like for you to consider the bigger picture. After our conversation, I went and checked many of the active people on Twitter who I know personally, or some who I know of and I noticed something interesting. The number of followers, closely aligns with the number they follow. In some cases it's nearly 50/50. So for example, someone who has 30k followers is also following back nearly 30k.
